ABSORPTION OF LIGHT IN GASES
Abstract
Two methods of measuring optical molecular absorptivities in gases, potentially capable of approaching theoretical sensitivity limits of 10 to the minus 8th power/cm were studied. An acoustic method was pushed experimentally to a sensitivity of 10 to the minus 5th power/cm absorptivity. Practical obstacles to further improvement have been found for the acoustic method. The second method, a laser illuminated spectrophone, was also investigated. Its performance was much closer to the theoretical limit.
